# calc_aqg_modes: Calculate Aquagram - Modes In bpollner/aquap2: Multivariate Data Analysis Tools for R including Aquaphotomics Methods

## Description

The following values can be provided to the argument `aqg.mod` in `getap`, specifiying what type of Aquagram should be calculated.

XXX

## Possible Values

Possible Aquagram modes are

• `classic`: The classical aquagram - smoothed, MSC, normalized

• `classic-diff`: same as above + one group subtracted from all the others.

• `sfc`: "Scaled, foreign center": smoothed, MSC, centered on the mean of selected calibration data, scaled.

• `sfc-diff`: same as above + one group subtracted from all the others.

• `aucs`: "Area Under Curve Stabilized": the area under the curve (auc) from the spectra in all the 12/15 coordinates in a set of calibration data at varying temperature is calculated, then divided by the total auc. Then the smalles and biggest value is taken as 0 calculated for every sample, and its value in percent ... XXX

• `aucs-diff`: same as above + one group subtracted from all the others.

• `aucs.tn`: aucs + temperature normalization: .... XXX the auc from a sample at Texp gets subtracted from all the auc of the samples.

• `aucs.tn-diff`: same as above + one group subtracted from all the others

• `aucs.tn.dce`: same as aucs.tn, but the scale calculated to show degrees celsius equivalent

• `aucs.tn.dce-diff`: same as above + one group subtracted from all the others

• `aucs.dce`: same as aucs, but the scale calculated to show degrees celsius equivalent

• `aucs.dce-diff`: same as above + one group subtracted from all the others
